I would like to invite you to the United States of America to stay with us for three months. It would be very nice to have you with us.A letter of invitation is a signed letter from the family member or friend who you will be staying with during your trip to the United States. A white card with gold calligraphy that reads 'To my wonderful brother on my wedding day' with a small heart symbol at the bottom. You can indeed invite your parents and siblings to your wedding, however, they will need to each apply for and obtain "visitor visas" to travel to the USA. You are cordially invited to my brother's wedding. We look forward to celebrating with you. To help you extend invitations, we have samples on how to write a letter to your friend to invite to your brother's wedding for you. If you are inviting them for the purpose of attending a wedding, they can apply for a tourist visa. Explain why you're inviting the person and how you plan to support them during their stay.
